I have an an engineer asking to provide a sprinkler under the first
landing of a non-combustible stairwell. The spec for the job states that
"Sprinkler shall be installed at top of shaft. Space below first landing
is considered concealed, non-accessible, non-combustible, and hence does
not require sprinkler protection."
he engineer who is reviewing my plans sent me an email stating the
following:
*8.15.3.2 Noncombustible Construction.*
*8.15.3.2.1 *In noncombustible stair shafts having noncombustible stairs
with noncombustible or limited-combustible finishes, sprinklers shall be
installed at the top of the shaft and under the first
accessible*landing*above the bottom of the shaft.
We always took this to mean the sprinklers are required under the first
landing? And by accessible we took this to mean access could be provided
by a access panel.."
Is this the way I should be interpreting the code? Do I still have to
sprinkler under the landing and make sure there's an access hatch? or
should I be able to omit it like the spec indicates?
I have been following this forum for a while now. This is the first
question I have posted.
